  "textContent": "For the first time, scientists have observed how tiny metal \"thorns\" called dendrites sprout inside lithium-ion batteries, which can cause the batteries to short-circuit. Their findings, published in the journal Science, shed light on previously unknown mechanical properties of lithium dendrites as they grow.",
